P T E N T QFIQE DEFECATOR Application October 19, 1934, Serial No. 749,069

11 Claims.

My present invention relates to defecators particularly of the lateral outlet type.

The general principles of the structure and operation of the types of defecators described in my present application are set forth in my copending application Serial No. 733,259, filed June 30, 1934, and entitled Defecators.

The invention is applicable to defecators inclusive of water closet bowls,urinals, and hospitals and other sinks, dental, medical and other sanitary bowls, and other receptacles, advantageously having an outlet at a lateral side, and provided with suitable means for the supply of water or equivalent efiluent, affording under sanitary conditions a mass of fluid for the well portion of the defecator, serving to receive solid and, or semi-solid and/0r fluid matter to be evacuated, and for the further purpose of flushing the defecator to discharge such flowable mass into a soil pipe or equivalent, the stated parts being coordinated to effect the respective operations under the condition of substantial absence of sound.

Embodiments of my invention may be generically classed as of the type frequently referred to as the wall-hung type, but such nomenclature as may be applied to my invention is indicative merely of the adaptability of embodiments of my invention to be positioned at or approximate a wall, since, as appears more fully hereinafter,

defecators embodying my invention may be positioned at any location independently of the location of a wall and may be suitably supported other than by or in proximity to a wall.

Marked advantages are possessed by embodiments of my invention by reason of the operation of the discharge by water and air pressures and water and air momentums effective conjointly during the discharge stage. By reason of such coordination of water and air pressures and of water and air momentums the amount of water required to effectuate the discharge is reduced to a minimum. Furthermore, defecators embodying my invention may be operated at mini- 4 mum pressure of water or other supplied effluent.

Such coordination of pressures and momentums respectively exercised by the air and the effluent bestows upon embodiments of my invention the optimum quality of silence in operation.

5 Essential characteristics of preferred forms of my invention reside in imparting by the supplied effluent to the after-fill a vertical movement and conjointly therewith an upfiow movement through the trapway, to effect the discharge of Such vortical movement creates a momentum of the fluid mass within the well of the bowl, a component of the force of such momentum assisting the force of the upflow movement through the trapway, attended by the lowering of the central area of 5 the fluid mass within the well and resulting force exercised by the downwardly directed current of air, such central lowering of the fluid mass effecting positive force upon matter contained in and including all floating matter toward and 10 through the intake and upwardly of the trapway.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying draw-- 15 ings, in which Fig. 1 is a top plan view of a preferred embodiment of my invention.

Fig. 2 is a central vertical section of Fig. 1.

Fig. 3 is a transverse vertical section on the 20 line 33 of Fig. 2, viewed in the direction of the indicated arrows.

Fig. 4 is a detail sectional elevation on line 4-4 of Fig. 2, viewed in the direction of the indicated arrows. 5

Referring to the drawings, the bowl l8 and the 2 coordinated parts are representative of any suitable form of defecator adapted to my invention.

The bowl I8 is shown comprising generically an upper portion If and a lower or well portion I2. The normal level of the mass of water l3 or other matter-receiving and effluent fluid, known as the after-fill, is indicated at I4.

Suitable provision of means are incorporated in the bowl affording an initial mass of water or other efiiuent serving as the after-fill for receiving any solid and/or semi-solid and/or fluid matter, and further providing upon the supply of the efiluent to insure the discharge of such flowable mass, such provision of means being embodied in the appurtenant parts of the bowl to be wholly operative at minimum pressure and minimum quantity of the effluent conjointly with engendered currents of air, to impart silence during the period of discharge. 45

Such provision of means includes a trapway or up-flow leg indicated at l5 and a dam or weir [6 effective to seal a portion of the mass of the efiiuent in the trapway I5.

Such up-flow leg I5 is afforded by the inwardly 5 disposed ledge l8 extending downwardly toward the well portion 12 of the bowl, its terminal portion I80; being disposed in predetermined relation vertically and horizontally with respect to the central area of the well portion l2, as appears more fully hereinafter. The upper rearward portion of the up-leg I5 is defined by the septum I9 terminating in the wall formation of the discharge opening 20, for the reception and securement therein of a suitable evacuator (not shown). Any suitable type of connection between the receiving end of such evacuator and the wall formation 20 of the discharge opening of the up-fiow leg I5, may be employed.

The stated ledge I8 extends upwardly as indicated at I8b to serve as a septum to define one side of the main water channel 22, the inflow port 23 of which may have any suitable wall formation adapted for a connection with any suitable supply of water or other effluent, such as a gravity water tank or a nipple provided with a flush valve, for supplying water from a domestic or local pressure water line, pressure tank, etc.

Such main water channel 22 is defined at its lower portion by the stated septum I9. The upper or top wall 24 of the main water channel may be afforded by the rearward horizontal ledge or shelf of the bowl.

The bowl proper may be supported in the indicated substantially horizontal position in any suitable manner. Advantageously, the bowl is supported by attachment to a wall indicated by the line .25, the material of the bowl proper being extended for such form of support, viz., by a rearward vertical web 26 extending to a vertical back plate 21, which extends substantially parallel to the face of the wall 25 and substantially normal to the web 26.

The upper bowl portion II is preferably of multi-conical formation, as shown; however, certain essentials of my invention are not limited to the illustrated form.

Preferably, the uppermost portion Ila inclusive of the web I8b is inwardly concave, receding from the vertical plane with respect to the effective area of discharge of the rim openings 28 provided for in the rim formation 29, the effectiveness of such relationship being set forth hereinafter. The rim formation 29 includes the rim channel 30 which extends about the top of the bowl and has an intake port 3| communicating with the main water channel 22.

An essential feature of each rim opening 28, in its preferred formation, is its discharge outwardly relative to the mean center of the bowl, whereby any matter possibly deposited on the inner face of the wall, particularly the back wall I8b of the upper wall portion Ila of the bowl,

is subjected to a quasi-chiseling action by the jets of water discharged through the rim openings. Such preferred form of rim jet discharge may be employed for the forwardly disposed rim openings 28, and/ or at the sides of the bowl.

The rim openings, particularly of the sets thereof disposed about the sides of the bowl, further, are directed to cooperate with the vortex jet of the main discharge flow means of the bowl, later described, to initiate and/or enhance such vortical movement of the fiowable mass I3.

A particular structural feature of my present invention is the provision of a main jet discharged through the discharge opening 32 directed substantially centrally of the mean axis of the upflow leg and located relative to the well I2 of the bowl opposite to the location of the entrance I5a of the up-fiow leg I5. Preferably, the volume of the jet discharged through the main jet opening '32 is relatively large, to thus impart sufiicient momentum to the jet to insure the desired results of evacuation of the contents of the bowl upwardly through the up-flow leg I5 and thence through the discharge opening 20 into the down siphon leg or other suitable passageway to the soil pipe or equivalent.

Preferably, such main jet and its required flushing medium is supplied by the provision of the channel 320. extending internally of the bowl material and communicating at its entrance 32b with the rim channel 30. Thus, the flushing fluid is supplied from the main water channel 22 respectively through the two rim channels 30 jointly in communication with the entrance 32b of the main jet channel 32a.

Such main jet channel 32a, see Figs. 1 and 2, is formed, as by proper coring, within the material of the bowl, the exposed face of the upper Wall 320 of the channel being a part of and conforming in contour with the lower disposed conical portion Nb of the interior of the bowl proper, whereby the contour of the wall 320 of the main jet channel 32a forms a substantially smooth configuration of general conical contour with the remainder of the lower wall III) of the interior of the bowl, inclusive of the upper wall I8 of the up-fiow leg I5, the pitch of the conical portion including the exposed face of the wall 320 being less than the pitch of the rearward wall portion I8, and the whole of the stated conical portion IIb being interrupted solely by the opening I2b of the well.

A primary functional feature of the discharge projected through the main jet 32 resides in the propulsion of the body I3 of the effluent and its contents in substantially rectilinear direction and substantially uniformly distributed relative to the entrance I5a of the up-fiow leg I5, as will appear more fully hereinafter.

As appears from the preferred embodiments of my invention, as illustrated in the drawings, the opening of the jet 32 is non-cylindrical, preferably fiat and having its longer dimension extending horizontally, and as above indicated having its vertical central plane substantially in alignment with the vertical central plane of the entrance opening I5a of the up-flow leg I5.

As appears from the embodiment shown in the drawings, by locating the bottom of the main channel 32a and the lower face of its opening 32 in rectilinear alignment with the bottom face of the well portion of the interior of the bowl and in like relationship with the entrance opening I5a of the up-flow leg I5, minimum resistance to the flow of the main jet is encountered, thus utilizing to the optimum the combined momentum effect of gravity added to the momentum of the eflluent at the stage of its entry into the entrance 32b of the main channel 32a, an effect comparable to water flowing down a hill into a shallow valley and up and over a lower hill, all the surfaces of which are smooth.

In combination with the stated main discharge, I further provide suitable means for effecting a vortical movement of the mass I3 of the effluent, as by means of the vortex jet 33, serving say to impart a vortical movement in counterclockwise direction, indicated by the arrowed line 33a. An effective means of supply of the vortex jet 33 is had by a passageway 34, shown having its entrance 34a. communicating with the main water channel 22 and extending interiorly of the wall portion I8 of the bowl proper.

Preferably, as appears in the drawings, the well formation I2 at the bottom of the bowl proper has its lowermost portion l2a disposed rearwardly of the center of the well opening I21) and in the direction toward the up-flow leg l5 and preferably within the entrance l5a of the upflow leg l5. By such provision of means, solid and semi-solid matter received within the after fill constituting the mass 13 of the effluent during the period of quiescence of the eflluent l3 subside towardthe depressed portion l2a of the well, thus being located under optimum conditions for direct entry within the entrance opening i500 and to a definite extent within the passageway of the up-flow leg 15 in advance of the discharge of the main discharge jet through the jet opening 32.

The well portion l2 preferably has its entry opening 121) of an effective cross-sectional areameasured by horizontal plane passing through the tip l8d of the wall l8- -less than the crosssectional area of the mouth and/or posterior portions of the up-fiow leg l5, to thereby serve as restriction means for preventing objects from entering the trapway which would not pass 1 through the up-flow leg l5 and/or the evacuator connected to the discharge opening 20 of the upflow leg l5 and forming therewith the siphonic passageway for the discharge of the contents of the bowl during the period of flushing.

Preferably, the up-flow leg is oval in cross-section and rises at its bottom face from the entrance opening Ilia to the dam or weir IS without change insize and without change of its angle of inclination, thus reducing to a minimum friction in the movement of the eflluent and its 35 contents during the stage of flushing.

Based upon the results of the tests I have made with practical full size embodiments of my invention, and utilizing solely the main discharge jet projected through jet opening 32, I have discovered that the jet discharge imparts positively an effective upward propulsive movement of the efiiuent, (also when having immersed therein testing objects such as rubber balls, irregular masses of sponge rubber, irregularly squeezed masses of paper, loose paper and the like in simulation of material present in the practical operation of my defecator) continuously upwardly through the up-flow leg l5 and continuously over the dam l6, thus in positive complete discharge through the trapway, and without any tendency of back flow. Such movement is effected without substantial lowering of the level Id of the mass iii of the effluent within the bowl pro-per andwithout unsealing the trapway, and accordingly without any gurgling or other noise normally attending the breaking of the seal.

Preferably, the downwardly extending halfwith the up-flow trapway leg 60 tion set forth in my copending application, Serial No. 4,620, filed February 2, 1935 and entitled Evacuators, now U. S. Patent No. 2,055,470, granted September 29, 1936.

For the purpose of the present application, my preferred evacuator extends downwardly, desirably of a general Z configuration, to a point substantially below the level of the well of the bowl, to provide proper siphonic action during the stage of the flush discharge of the bowl, the uppermost portion of the evacuator being bulged outwardly to provide for a relatively large volume therein, the evacuator at a central portion being restricted in cross-sectional area with respect to its upper inlet, such constricture serving dually as a seal against entry of air in reverse direction through the evacuator from the soil pipe or other eventual discharge, and also to effect the entraining of air from the interior of the stated upper bulged portion to effect the condition of sub-atmospheric pressure of the air retained in such upper bulged portion, the lowermost portion of the evacuator, i. e. posterior of its stated constricted central portion, being constructed to transform the flow of the discharge efiluent into a curtain, serving additionally to maintain the seal within the upper bulged portion against the stated inflow of air through the evacuator in reverse direction.

Pursuant to the more preferred forms of my invention, the vortical movement engendered by the discharge through the vortex jet 33 is carried out without substantial rise of the level M of the mass l3 of the efliuent and contained matter. The preferred forms of my invention embody the vortex discharge jet disposed a substantial depth below the level I4 of the mass 13 of the eilluent, such arrangement effecting two essential functions, namely, to impart positive vortical movement to the mass l3 and to effect the discharge through the vortex jet 33 without noise. If desired, the jet opening may be directed downwardly relative to the level M.

The rim channels 30, 3D communicate respectively directly with the main water channel 22 and discharge respectively into the main jet channel 32a, the rim channels 30, 30 serving also to supply efiluent to the respective jet openings 28. For the purpose of providing a relatively large mass of the eiiiuent and maximum effective momentum of the effluent through the main jet 32, including the reduction of friction to a minimum and substantial elimination of noise, the rim channels 30, 30 are formed of relatively great depth, as is apparent from Fig. 3, and also from Fig. 2, and having their respective upper interiors 30a, 30a large relative to their respective lower interiors 30b, 3017-, the communication with the respective rim openings 28 had by communication of their respective entrances with the rela tively large upper interiors 30a, 30a. By such provision of means, upon initiation of the flushing operation, the eflluent passes rapidly and in relatively large volume firstly through the lower interior portions 30b, 30b, displacing the air therein upwardly into the relatively large upper interiors 30a, 30a gradually, causing the displaced air to pass through the respective rim openings, whereby the displacement of the air is effected without substantial noise and without substantial trapping of air therein, and the further deslderatum that the supply of the efiiuent to the rim openings takes place subsequent to the stage of effective operation of the main discharge jet.

The operation of my invention will be largely understood from the foregoing. Suffice it to add, that upon flushing the defecator, the effluent flowing into the main water channel 22 passes directly downwardly into the passage 34 leading to the vortex jet 33. Upon further filling of the main vortex channel 22, the effluent passes into the respective rim channels 30, 30, continuing downwardly through the main jet channel 32a and thus through the main jet opening 32.

At this stage the vortical movement of the mass l3 of the eilluent and contained matter has been set in operation, accompanied by a lowering of the central portion of the mass l3 arising from such vortical movement combined with the posiv tive projection of the portion of the mass l3 'withof the effluent and contained matter upwardly through thetrapway l5, over the dam I6, and thus into the soil pipe or equivalent discharge means. Such lowering of the central portion of the -mass enhanced by the general conical contour of upwardly increasing radius of the inner face: of the bowl, brings about an increase of the atmospheric pressure upon the mass, which increased pressure is effective downwardly upon the mass and accordingly effectual in propelling the mass upwardly-of the upflow discharge leg I5.

The above kinetic forces imparted by the flushing eifiuent to the mass I3 is further accelerated by the forces engendered by the currents of air arising from the setting of the mass l3 into vortical movement and the stated upflow movement of the mass through the up-flow leg l5.

Subsequent to the setting in operation of the stated vortical movement by the vortex jet 33 and the stated positive discharge through the up-flow leg I by the main jet 32, the further rise of the water in the main channel 22 supplies eiiluent to the respective rim openings, which as hereinabove referred to, combine with the vortex jet 32 to maintain the mass within the bowl in vortical movement, as well as to scour the sides of the bowl.

Toward the stage of shutting off of the supply of the efiiuent to the main water channel 22, the completion of the discharge of the bowl will have taken place, following which air enters through the entrance of the up-fiow leg l5, thus causing a breaking of the siphonic action, and part return of the efiluent in the up-fiow leg which with the remainder of the supplied eflluent flowing throughthe rim openings, referred to above, and through the passage 34 and out of the vortex jet 33, provides for the after-fill of the effiuent l3, preparatory for the next operation of the defecator.

The rim openings 28 are preferably of the general shape of an inverted L, extending at an angle, say 30, to the vertical, inclined in correspondence to the direction of the vortical movement effected by the rim openings in combination with the vortex jet 33. The most preferred form of the discharge opening outlet of each rim opening is outwardly tapered, i. e., extending laterally of the axis of the opening, to thereby more effectively chisel matter deposited upon the sides of the bowl. The most preferred form of the inlet of each rim opening 28 is inwardly tapering, thereby facilitating the entry of the air displaced upon flow of the effluent through the lower portion of the rim channels 30 in transit to the main jet channel 32a, which function is enhanced by the outwardly divergent formation of the discharge opening of each rim opening.

The bowl and the stated component parts may be of vitreous material suitably molded and otherwise treated, or of cast metal or other proper material, enameled or otherwise appropriately surfaced and/or suitably treated. The defecator illustrated in the drawings, and to scaled dimensions, has been designed for manufacture of porcelain, suitable provision being made for the proper coring of the channel parts, allowance of shrinkage of the material ensuing during the baking stage, etc. The stated preferred form of the rim openings is conveniently had by drilling through the uppermost wall of the rim 29 during an intermediate baking stage, the thus formed drill openings in the upper wall of the rim 29 being later plugged with the porcelainforming 2,066,882 in the well per se, thus effecting the positive flowmaterial to eradicate the of the bowl.

Commercially produced embodiments of my in vention operate efficiently with a supply of water at the low head of six inches and at the low flow volume of four gallons, delivered, for example, from a regulation open flush tank; such embodiments of my invention operate also highly satisfactorily at three pounds pressure and correspondingly reduced rate of flow of water furnished by a suitable supply under control of a regulation pressure valve.

As above stated, the contour of the up-fiow leg I5 is preferably oval, and most preferably such oval contoured up-flow leg is positioned to have the larger axis ofthe oval disposed substantially in horizontal plane, that is to say, the bottom face and the top face of the up-fiow leg l5 are substantially flat, as shown in the drawings.

Also, as shown in the drawings, the rear portion of the ledge 24, particularly its central area inclines upwardly, as indicated at 2411, to serve as a splash guard. Desirably, the vertically extending upper portions 24b also serve to support the bowl, as by provision of bolt holes 35, 35, whereby the bowl is supported in weight and during the stages of load, independently of the connection of the bowl to the waste pipe.

A most preferred form of the bowl, based upon my observations of tests carried out with full size commercial embodiments and under regulation commercial conditions, is that shown in scale in the drawings; I have particular reference to the formation of the walls of the bowl proper, and note that the side walls of the uppermost part of the bowl, indicated by Ha in Figs. 2 and 3, have substantially vertical faces, and that the lower and lowermost parts of the bowl proper, indicated by lib, have faces of general conical contour of graduately decreasing radius converging to and terminating at the well hole, the pitch of the respective decreasing radii of the conical portion toward the front of the bowl being less than corresponding radii at the rear of the bowl. In general, embodiments of my invention, as appears from the foregoing and also from the preferred embodiment illustrated in the drawings, have the faces of the interior of the bowl above the mouth of its well portion substantially smooth and of general conical contour solely increasing in effective radius upwardly without increase of the rate of increase of the radius in the vicinity of the normal level of the contents of the bowl, to thereby avoid re-entrant wall formation in the stated vicinity.

Further, the front of the well hole, indicated at I20, slopes toward the bottom of the well hole in the direction toward the inlet [5a of the upflow leg l5, and the back of the well hole, indicated at l2d, recedes toward the inlet l5a of the up-flow leg l5.

Whereas I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention.
